The front of the case has ventilation holes for the dual fans behind. In the middle is a star shaped cutout for a tri-color LED. The back has a power switch, two FireWire ports, a USB2.0 port, and a power connector which resembles PS/2 plugs. Both 5V and 12V lines are necessary to power the HDD, the fans, and the circuitry. The case is comprised of an outer shell and an inner tray; they're held together by a pair of rather small screws. Once removed the inner tray slides out.
